Fifa said yesterday that its disciplinary committee is considering opening a case. It will also consider a report by the Fifa match commissioner, Eggert Magnusson of Iceland.

‘We always take any evidence or submissions to our disciplinary committee. It is the disciplinary committee that will meet,’ a spokesman told The Guardian.

‘If they see any grounds they will open proceedings. Then it is up to the disciplinary commission to take the decision.’

The shirtless fan, who is reportedly from Poland had an email address and telephone number written on his back.

Ghana’s former Portsmouth and Sunderland midfielder Sully Muntari, who currently plays for AC Milan, embraced the pitch invader before being detained by stewards and removed from the field.

Brazil’s organising committee spokesman Saint-Clair Milesi said the man was detained by local authorities.
